Sceptic not sure about apostle (8,6)
I believe the answer is:
doubting thomas
This could be a double definition.
'sceptic' is the first definition.
(synonyms)
'apostle' is the second definition.
(I know that doubting Thomas is a apostle)
'not sure about' acts as a link.
I am not very happy about this link. Some or all of it may belong to one of the definitions.
Can you help me to learn more?
(Other definitions for doubting thomas that I've seen before include "needed proof of life after death" , "sceptic" .)
